If the pair can be taken both in front, then I shoot tight barrel first then open second. If they have to be taken one in front and the second going away I shoot open first the tight second but I wait until the first is as close as possible before I shoot, even if this makes the second shot harder. Better to make one good shot than miss two bad shots. If both have to be shot as going away I shoot the closet one first with the open choke and most likely not shoot at the second bird. I hate going away shots that are at a great distance. It is a very hard angle to kill a bird and I see too much cripling from such shots. Of course my hunting partner might point out that I rarely hit both birds in such a pair but since his paws are too big to type I have to admit it myself.
It gets more copmplex when you load two different size shots. Have to remember which is large and which is smaller. I have hunted areas that you could put up a pheasant or quail just depend on luck of the day. Late season I tend to load two differnt shell types to cover as many possible needs as possible.
